So far so good. Wanted to leave a review as there were none on this product before i bought it. Arrived in two days and although was dubious if it would work (these are not standard cables and are not manufactured by Microsoft. Therefore you can only get these cables as third party versions.....like this one) i plugged it into my intocircuit power castle pc26000 battery bank (also purchased on Amazon) and it was charging straight away. Magnetic seal works fine and seems very good quality cable with no visible cut or solder marks. Will be interesting to see how long it last but at the very first use, definitely deserves 5 stars.
